This invention isa sni ble and improved brief case adapted to interchangeably receive and deta'chably retain carrier means to which 0 Claims. (Cl. lac-1.0)

is permanently fastened a loose leaf binder. The

a yieldable substantially U-shaped 'carrier only.

and disconnectibly securing the carrier within and to the brief case by complementary and disengageable snap fastener elements secured to the carrier and the lining of the brief case however independent of the means permanently securing the binder to the carrier only. Another important object is concerned with a new article of manufacture wherein the loose leaf binder is secured permanently along'the medial or intermediate portion only of the flexible carrier.

having spaced snap fastener elements secured thereto but independent of the means securing the binder to the medial portion. Another object is to secure the loose leaf binder within the U-shaped flexible carrier having sides straddling the sides of the binder and adapted to be conveniently grasped and urged outwardly for separating the carrier or protector from the brief case. Another object comprehends prompt exchange or substitution of a carrier secured within the brief caseby another binder sustaining carrier,.that is, the invention provides for the ultilization of interchangeable carriers of the type ailuded to and severally cooperating with the same brief case, thus enhancing the utility of. the latter although permitting convenient replacement of one carrier and its fully or partially loaded ring binder by another carrier-with an empty or partially loaded binder. Another object can'- templates the provision of a carrier disconnectibly associated with the brief case and constituting means for partially or fully covering the sheets of paper mounted on the binder. Other important objects and functional and structural features, advantages, and aspects of the invention will appear from the following detailed spec iflcation taken with the accompanying drawings wherein:

Fig. 1 is a plan view of the brief case according to my invention shown open and illustrating the loose leaf binder closed.

Fig.2 is a transverse vertical sectional view as z. on the line 2-2 of Fig. 1, however showing the carrier disconnected from the medial portion of the brief case.

P18. 8 is a rear view of the carrier.

Fig. 3A isa fragmentary and broken view of Fig. 1 depicting the brief case open and without the carrier.

Fig.4 is a view taken on the line 4-4 of Fig. 2. and a I Fig. 5 is a view showing the carrier illustrated in Fig. 4 however slightly modified.

Illustrative of the embodiments disclosed the brief case or container BC is provided with an inside and fixed lining L having the medial portion M to which is permanently fastened the spaced keepers or sockets K adapted to resiliently but removably retain and interlock with spaced posts P desirably and permanently secured to the medial zone of the flexible but relatively rugged and stiff carrier C to which is permanently fastened by the rivets R a conventional loose leaf ring binder generally denoted LL having spaced and split rings SR adapted to be opened or closed on actuating the end triggers T as is well under stood.

a More particularly the spaced posts P are permanently anchored to the flexible carrier C only and depend from the medial or intermediate portion thereof. The spaced keepers K are permanently secured to the inside medial portion of the lining L which is desirably fastened to the brief casein any wellknown manner. Posts and companion keepers K may be considered as pairs of complementary and disengageable snap fastening elements or members of the conventional type. The spaced posts or elements P are fixed to and depend from and are spaced longitudinally of the carrier C although permanently secured thereto independent of the spaced rivets it permanently anchoring binder LL to carrier C. These rivets as shown are near the ends of the ring binder LL. By the arrangement disclosed the carrier if held locked to and within the brief case by the complementary snap fastening elements may be readily detached by grasping the yieldable or flexible sides S (Fig. 4) and even the intermediate portion of the carrier and urging the latter in a direction away from the inside medial part of the brief case. This action unlocks snap fastening elements P and K to permit bodily lifting of the carrier and binder out of the brief case and more specifically away'from the lining L. Of course the carrier or protector C may also be considered as an intervening link between the binder and the brief case although aspreviously stated the binder is secured to the carrier only independent of the depending but spaced snap fastener elements P which in cooperation with the companion snap fastener elements K detachably retain the carrier to and within the brief case. In Fig. 4, the carrier C is shown detached from the brief case. By aligning the complementary snap fastener elements Pover companion complementary snap fastener elements K, these elements as is well understood may be quickly interlocked, thus holding the carrier retained within the brief case and in all the forms disclosed the carrier or protector C is disposed longitudinally of and under. the binder and preferably has its sides extend-,.

ing laterally of and straddling'the latter.

With the expanded or tapered heads of the spaced posts P interlocked with the keepers K, the carrier is prevented from shifting relative to the lining and the triggers T may be conveniently operated to permit the insertion or removal of the sheets of paper PP on or from the rings SR.

Where these rings carry an ample load or stack of paper, the carrier may be quickly disengaged or separated from the lining L and another carrier C of the type shown in Fig. may be substituted and quickly snapped on the spaced keepers K.

In the form according to Figs. 3 and 4 the sides S of the carrier C which may be of a suitable leather or an imitation thereof slightly overlap and straddle the sides of the stack PP whereas in the embodiment according to Fig. 5 the sides or margins S fully straddle, cover and protect the sides of the stack of paper PP. In other aspects the form of carrier shown in Fig. 5 is along the lines according to the form exhibited in Figs. 1-4 and corresponding parts have been primed although in all of the forms disclosed the sides or wings as S of the U-shaped flexible carrier or protector if heldlocked to the brief case, may be readily disengaged therefrom by grasping the sides thereof and applying a thrust in the direction away from the ling L, that is, the carrier to which the binder B is permanently secured by the spaced rivets R is snapped off" the brief case. Conversely the carrier may be readily attached or snapped on the brief case. With the carrier attached to the brief case, the carrier is spaced from the medial part of the brief case and the carrier has its'intermediate portion intervening the carrier and the medial part of the case. Also as disclosed the snap fastener elements P extend in part below the intermediate part of the carrier while the snap fastener elements K project in part above the medial portion of the brief case.

Various changes may be made in details of construction and arrangement of parts without departing from the spirit of the invention or sacrificing any of the advantages thereof inherent therein. 4
